How to implement a "mutex" lock

[Former Member]

Hi there, I'm in a need of creating something like a mutex mechanism, not related to a table.

Is it possible or do I have to fill in any dummy table ?

Cheers,

Hi,

The status monitor for the integrated ITS (transaction SITSPMON) is used to display the current status of the integrated ITS functionality in the application server. You can display and change the currently set parameters. You can get information on the memory load, on the content of the ITS caches, on set locks and on activated features.

Functions
The different pieces of information displayed on the screen are sorted by categories, which you can view using the respective tabstrip. Currently, the following display screens are available:

·        Parameters

·        Memory Statistics

·        Template and MIME Cache

·        Mutex Locks

·        HTML Template Directory

·        Feature List


Mutex Locks
Mutex Locks (Mutual Exclusions) prevent competing access to resources. The integrated ITS function uses mutex locks for the HTML template cache, which exists only once for all work processes, to prevent the situation that a work process stores a new HTML template version in the HTML template cache while another work process processes an HTML template. 

Apart from this, mutex locks are used for

·        Memory statistics

·        Individual HTML template cache entries

·        HTML Template Directory

Try exploring how this functionality have been done in transaction SITSPMON.
